While investigating the ordering and magnetic dynamics in La2-xSrxCoO4 we found some intriguing behaviour for samples with small x, which would imply that the phase diagram is...

This proposal aims to characterise the spin dynamics of three Pr-based pyrochlores that may be realisations of quantum spin ice materials. The lower moment and larger wave...

The aim of the experiment is to study, in low magnetic fields, the very slow spin fluctuation (MHz range) present in the normal phase of La0.8Y0.2LaFe1-xMnxAsO0.89F0.11...

Common d5 pyrochlore iridates, A2Ir2O7 or A2Ir2O6O’, are reported to have long range magnetic order based on muSR experiment. Only Pr2Ir2O7 has been identified as a metallic...

We have recently performed zero field muon spin rotation (muSR) studies of one the shape memory alloy Ni2.04Mn1.4Sn0.56 on EMU spectrometer at ISIS and the observed results are...

The geometric frustration, combined with other parameters like the net quantum spin state (1/2, 1 or 3/2) is expected to give rise the exotic magnetic ground states such as the...

This study involves attempting to understand the Li atom diffusion within Li-intercalated hexagonal boron nitride. Muons present a significant advantage as they are sensitive to...
